NASA Space Station On-Orbit Status 31 May 2005

SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (copyright © 2005) to enhance access to related status reports and NASA activities.

All ISS systems continue to function nominally, except those noted previously or below. At wakeup, the crew was congratulated on yesterday’s Z1 cargo dome transfer operations.

Today, the crew took the CHeCS emergency medical operations OBT (on-board training) drill, a 30-min. exercise to refresh the Crew Medical Officer (CMO)’s acuity in applying ACLS (advanced cardio life support) in an emergency. [Today’s computer- and video-based proficiency drill focused on re-familiarization with the RSP (Respiratory Support Pack), the use of the defibrillator, and the CMRS (Crew Medical Restraint System).]

CDR Krikalev worked in the Soyuz TMA-6/10S descent module, troubleshooting the V2 fan in the Orbital Module (BO) to assure adequate air ventilation for the eventually upcoming relocation to the FGB nadir-facing port (ASPB). The activity was supported by specialist tagup via S-band. [As part of the troubleshooting, Sergei was to bypass the fan’s automatic switch (AP-1 V2) if the mechanical functionality check of V2 proved unsuccessful.]

FE/SO Phillips successfully reinstalled the RED (resistive exercise device) over the Node zenith hatch, from where it was removed yesterday to gain access to the Z1 “dome”. [After lubricating the components with Braycote-601, John put together two new and two old support block and pad assemblies and re-mounted the hardplate.]

Afterwards, the RED’s hardplate bolts were checked for tightness, a regular maintenance task done every 6 months.

John also did the weekly maintenance on the TVIS treadmill, primarily checking the condition of the SPDs (subject positioning devices) and recording time & date values.

Using new MEC (medical equipment computer) software, both crewmembers in turn took their second periodic on-orbit hearing assessment (O-OHA) test, a NASA environmental health systems examination to assess the efficacy of acoustic countermeasures. [The O-OHA audiography test involves minimum audibility measurements for each ear over a wide range of frequencies (0.25-10 kHz) and sound pressure levels, with the crewmembers using individual-specific Prophonics earphones, Bose ANC headsets and the SLM (sound level meter). To conduct the testing, the experimenter is supported by special EarQ software on the MEC, featuring an up/down-arrow-operated slider for each test frequency that the crewmember moves to the lowest sound pressure level at which the tone can still be heard. The baseline test is required not later than about Flight Day 14 for each new Expedition and is then performed once per month.]

The FE successfully removed a jammed “UltraBay” adapter from an A31p laptop (#1010), part of the SSC LAN (Station Support Computer Local Area Network) system. Additional checkout of the laptop is underway.

Both crewmembers conducted their regular 2.5-hr. physical exercise program on the TVIS treadmill, RED exerciser and VELO bike with bungee cord load trainer (NS-1). [Sergei’s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill and one hour on VELO plus load trainer (today: Day 4 of a new set).]

While the CDR was working out on the VELO, FE Phillips took photographs of the operation of the NS-1 force loader when the operator was pulling cords from pedals and from behind the back, plus of the machine without operator.

Afterwards, the FE transferred the exercise data files to the MEC for downlink, as well as the daily wristband HRM (heart rate monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium.

John printed out newly arrived procedures pages and incorporated them in their respective hardcopy books (1 Photo/TV Book, 2 copies of the X2R4 Warning Procedures Book).

In the Service Module (SM), Sergei switched the Vozdukh CO2 (carbon dioxide) scrubber to manual mode for power-down. Some time later, the ground activated US CDRA (CO2 Removal Assembly) in the Lab, for a performance check after its recent troubleshooting. ppCO2 is being checked with the MCA (Major Constituents Analyzer) that was taken through a 30-min. “zero” calibration yesterday.

Phillips completed the daily routine maintenance of the SM’s SOZh environment control & life support system, including regular replacements of the ASU toilet facility, and Krikalev prepared the regular IMS (Inventory Management System) “delta” file for export/import to the IMS databases.

Working off his voluntary task list, Sergei conducted another session with the “Uragan” (hurricane) earth-imaging program, focusing the Nikon D1X No. 3 digital camera with 800-mm lens on targets called out on an uplinked list. [Today’s targets included the Don River valley, a mapping survey of fields to the Volga River, the largest island on the Volga, with a drilling rig on its bank, oilfields, the Katun River valley, the Altai Mountains, a panoramic view of central Russia, the Astrakhan Gas Condensate Plant infrastructure (wells, roadways, pumping stations) on the eastern bank of the Volga left, the Amudarya River and Tajikistan river valleys.]

As a second “job jar” suggestion, the CDR still has urine transfer from the EDV-U collection container to the empty water tanks 1 and 2 of Progress 17 on standby.

At ~4:05am EDT, the crew downlinked congratulatory greetings to the local police department of Baikonur, part of the Russian Interior Ministry Directorate. [The militia/police at Baikonur (then Tyura Tam) was established 40 years ago.]

At ~10:55am, Phillips and Krikalev supported a 15-min. televised PAO interview via Ku-band & S-band with two Houston/TX television stations,- KHOU-TV and KRIV-TV.

During crew sleep tonight (10:50pm EDT), TsUP/Moscow will begin several hours of SM 7.03 software transition, which should complete the upgrade of the RS onboard computer system (BVS). Tomorrow morning, the Central and Terminal computers (TsVM, TVM) will be restarted, monitored by Krikalev with the Laptop 2 (LT2) and vers. 7.03.

Update on Solid-Fuel Oxygen Generator (SFOG) candles: Three more SFOGs (Russian: TGK) were used today, with one failing to ignite. As of tonight, a total of 17 candles of the old set have been decomposed on board since 5/20 (total attempts: 27 [i.e., 10 failures = 37% failure rate, instead of expected 20%]). With the actual failure rate, TGKs currently on board last for 24 days. Progress 18 (arrival 6/18) is manifested to deliver 42 “new” SFOGs (zero failure rate) plus 110 kg (242 lbs) of O2.

No CEO (crew earth observations) photo targets today.
